I have had my NVIDIA GeForce 7800 GT card in my rig for 3 years. I brought the computer to work, cause i needed a faster machine. I bought 2 more monitors, took the old Radeon 7000 card out of my work machine, and made a 4-monitor rig.
Everything was working fine, until i did a windows update (for Media Center - it was the Rollups)
The update also included "new" drivers for my card. So i (stupidly) ran the updates. Then everything crapped out.
My computer rebooted, and the Radeon card was fine. But when i go to adjust the settings on the NVIDIA card, it says that the drivers were written for a previous version of windows. Then it tells me that it can only run in VGA mode, and at that it runs 640x480 with 4-bit colors.
I re-downloaded and reinstalled the drivers for the NVIDIA card, but this time direct from NVIDIA's website. Then it told me it can't configure the card because i don't have administrator access. (Oh, yes i do!)
I pulled the card and put in a GeForce 9600GT. Same problem.
So i pull all the cards and just put in the GeForce 9600GT. Works Fine.
Now i just put in the GeForce 7800GT. Problem.
So i figure it's the card. (By the way, i changed out my 500Watt ATXPSU for a 650Watt ATX PSU along the way)
So i put the 9600 in with the Radeon. Now the Radeon has the problem! (The Radeon is PCI and the NVIDIA's are PCI-Express)
So i pull the Radeon and put in the 7800 with the 9600. The system doesn't get past the "Windows XP" splash screen, before it goes all BSOD.
So right now I'm running on the GeForce 9600GT with the 650Watt ATX. The 7800 and the Radeon Card are sitting next to me, waiting to be thrown in the trash.
Before i go spend more money on another 9600 GT to not have it work, is there any advice someone can give?
(By the way - googling this problem, gives me a Microsoft KB fix for exactly the problem. Except it's for SP2 and i'm running SP3.)

A constant beep, usually indicates the post is detecting no memory installed. This is usually caused by the memory not being installed correctly or incompatible memory. double check you have the correct memory for this mother board. If you have 2 chips, install one and test. If this does not work swap the memory and try again. If both chips fail, you might try a different brand of memory.
If you installed total 4GB memory, the system will detect less than 4GB of total memory because of address space allocation for other critical functions, such as:
- System BIOS (including motherboard, add-on cards, etc..) - Motherboards resources - Memory mapped I/O - configuration for AGP/PCI-Ex/PCI - Other memory allocations for PCI devices
Different onboard devices and different add-on cards (devices) will result of different total memory size. e.g. more PCI cards installed will require more memory resources, resulting of less memory free for other uses.
On a SLI system, since PCI-Ex graphic cards will occupy around 256MB, another 256MB will be occupied after you install a 2nd PCI-Ex graphic card. Hence, 2.75GB memory left only if two SLI cards installed on A8N-SLI Premium while 3.0GB memory left with one graphic card without other add-on devices.
This limitation applies to most chipsets & Microsoft Windows 32-bit version operating systems.
If you install Windows 32-bit version operating system, we recommend that you install less than 3GB of total memory. If more than 3GB memory is required for your system, then below two conditions must be met:1. The memory controller which supports memory swap functionality is used. Chipsets later than Intel 975X, 955X, Nvidia NF4 SLI Intel Edition, Nvidia NF4 SLI X16, and AMD K8 CPU architecture support memory swap function.2. Windows 64-bit OS which can address more than 4GB memory.
It sounds like the front panel wire has either come loose from the motherboard or is plugged into the wrong spot. Recheck the motherboard to see if the wires are in the right place & not loose. Hope this helps.
I went through your bios manual three times & did not come across a setting that gives you the option as you listed above.
What I did come across & triple checked your Manual Pg. 2-28 section 14. Asus EZ selector card connector (144-pin SLI_CON. When using two PCIE SLI cards make sure the card is seated correctly & set for Dual Video Cards. (extreamly important). Pg. 4-34, section 4.4.9 SLI mode Recommend kepping to Auto. Than the Bios detects the setting of theSLI selector card.
Refering to the sentance above the manual recommends all settings be set to Auto. Your Bios will do the rest. If for unknown reason you no longer have your manual you can download it from Asus. You'll need to fill in the 3 windows under, Please Select the Product.

Hey, set the bios setting to auto. As far as I know and I have two 8600 GTs in my pc on sli I havent had to do such thing in the control panel. Directx diag reports 1008MB of videomemory for me. (both cards)
Havent had any problems myself Il test that when I get home tonight. Il provide you with more help incase I have to sort the same problem in my own pc.
Yes, you do. Your board was built with the idea to use 2 graphic boards to get great video
